It should be stated right up front that while GagSchool does claim to be an exclusive content site, it really isn't. Initially, it began as one, but quickly started getting nonexclusive stuff and that content now makes up the vast majority of everything available. 

So far there are 125 face-fucking episodes available and each one comes with a downloadable video. All the movies are downloadable in good to superb quality MPEG format in their full-length form.  As you can tell, there is some variability here.

But wait, that is not even close to all you get with your membership. Your membership gets you access to the complete network of 28 other sites, including: Footjob Footjob, Creampie Models, Handjob Spectacles, Jerk Me Now, Jizz On Glasses, Handjob Models, Tit Job Models, Footjob Models, Big Black Pimp, Cock Loving Moms, Argentina Love, Teen POV Facials, Just CreamPie and GagOnMyCock. There is also a DVD archive with over 700 streamable movies.

If you want to see sweet chicks, treated like angels in erotic videos, then take your dick elsewhere. However, if, on the other hand, you are ready to watch sluts get their pretty little faces fucked till they gag and don't mind that it's mostly nonexclusive and updating slowly, then take your dick into Gag School and all the bonus sites that come with it. Warning: make sure you join for a full month, as the trial option will only give you access to one movie from each site!
